Title: An Improved Electric Battery Lamp.
Inventor: HAMILTON JOHN EDWARD
IPC: G08B5/38
Filed: 1916-07-25
Abstract: 107,773. Hamilton, J. E. July 25, 1916. Lamp signals.-A lamp particularly for railway guards is provided with a switch 5 which can be moved vertically to switch the light on and off and rotated horizontally to vary the colour of the light exhibited. A vertical movement of the switch brings the spring conductors 29, 21 into contact and completes the circuit through the lamp by way of the strips 30, 20 and the battery contacts 18, 19 the latter of which is in the form of a ring. An horizontal rotary movement of the switch 5 moves an arm 35 which carries frames 38 provided with different coloured glasses situated in front of the bulb 23 as shown in plan in Fig. 3. The switch is held in its different positions by a spring catch 39 which engages recesses in a block 44. The lamp is provided with two handles 3, 4, and the switch is of angular form and has a recess 45 to enable it to be operated by the hand grasping either of the handles. The lamp casing is divided into two compartments by a partition 12 which forms the top of an inner casing 9 which contains the battery. The bottom 13 of the casing 9 is hinged and locked when closed by a projection 14 engaging a slot 15 where it is held by a catch 16. The bottom 13 may be in the form of bars covered with rubber tubing 17. Two lenses 24, 25 are provided in front of the bulb 23, the arrangement being as described in Specification 104,847, [Class 75 (ii), Lamp chimneys &c.].

Title: Improvements in or relating to position sensing devices
Inventor: MYNALL DENNIS JAMES
Filed: 1956-01-31
Abstract: 814,617. Transformers. BRITISH THOMSON-HOUSTON CO. Ltd. Jan. 31, 1957 [Jan. 31, 1956], No. 3082/56. Class 38 (2). [Also in Group XXXVIII] Apparatus for determining the position of a tool relative to a workpiece comprises a cylindrical stator with a helical conductive winding on its external surface, surrounded by a coaxial hollow cylindrical rotor having a similar helical conducting winding on its internal surface, the mutual inductance between the windings being cyclically variable with relative axial movement, so that the instantaneous relative position can be determined by the instantaneous value of the mutual inductance. As shown, the stator 10 (Fig. 2) has on its outer surface two interlaced conductive helical paths 12, 13 connected together at one end by a wire 14 whereby any current flow would be in opposite directions in adjacent turns. The rotor 11 (Fig. 3) is similarly supplied with two interlaced conductive helical paths 15a, 15b on its inner surface, so that when the rotor 11 moves axially over the stator the mutual inductance follows a sinusoidal variation. A second conductive path, displaced by 90 degrees, may be added to the stator 10 and/or the rotor 11 to produce a cosine variation of mutual inductance. The rotor 11 may be a halfcylinder, the interconnection between turns being made on the outer surface, or by short connecting links between adjacent half-turns. The members 10, 11 may be other than circular cylinders, e.g. oval, and the axis may be other than rectilinear, e.g. curved to determine angular displacement. Relative angular rotation between the stator about a rectilinear axis can also be measured. The members 10, 11 may be insulating material, or ferromagnetic material, and the conductive paths may be printed or consist of strips or wires located in grooves.

Title: Improved protective arrangements for mine hoists
IPC: B66B19/06
Filed: 1942-03-11
Abstract: 555,518. Signalling systems for mines. LAMB, E. L. LE, SMITH, E. K., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. March 11, 1942, No. 3224. [Classes 40 (i) and 118 (ii)] Control equipment for a mine hoist comprises an electrically operable safety device permitting operation of the winder, the circuits of the device being controlled jointly by the usual electrical mechanical, hydraulic or like signalling system and a " men-safety " device so that if " men-riding " is signalled the electric device and winder will not operate unless the driver has operated the " mensafety " device which brings in winding conditions suitable for winding men. The " men-riding " signal given by a banksman, in a manner not shown, closes contact S1 which releases a normally operated relay R1 and lights lamp L1. Other contacts S2, S3 are operated to function in a similar way when an onsetter gives the signal. The electrical safety device C1. when operated connects up the power and permits application of the brake and is normally operated over the usual safety switches A-C (controlled by overwinder, speed &c.) in series with contacts OP1 closed when the main control lever is " off " and, if desired, contacts BIS closed when the brake lever is " on." When contacts OP1 and BIS are opened to start a wind of material, the circuit of C1 is maintained over C2a, C3c which are respectively contacts of contactor C2 energized over contacts of R1-R3 providing " men " is not signalled and of a contactor C3 which is de-energized until " men " is signalled. Considering the circuits so far described, a " men " signal opens the branch C2a, C3c so that unless C1 is maintained over the " men-safety " device contact in series with its own contact, the winder will be inoperative, but 'can be brought into operation by re-operating C1 over OP1 and BIS, followed by MS and then re-starting. The circuit of contactor C3 includes normally closed contacts LS2 momentarily opened when a tub is passed into the cage so as to release C3 (operated for " men ") when winding of material is resumed. If a " men " signal is received when material is being wound the circuit of C1 is maintained until the end of the wind by contacts C4b of C4 which is operated over a friction switch FS during a wind. In order to permit small adjustments of the cage level at the bank, the circuit of C1 is maintained even with " men by a contact LS1 closed when the cage is at or near the bank.

Abstract: 575,041. Supply and power meters. SHEPHERD, G. R. (Westinghouse Electric International Co.) Feb. 22, 1944, No. 3252. [Class 37] In order to provide a source of auxiliary power, one of the coils of an induction meter is overwound with a secondary winding comprising a ribbon conductor. Fig. 1 shows a single-phase induction meter 1 associated with a thermal maximum demand meter 2. The maximum demand meter 2 includes a pair of bimetallic springs 13, 14 mounted on a common shaft 15 for actuating a pointer 16. The springs 13, 14, when heated, tend to rotate the shaft in opposite directions. The bimetallic spring 13 is heated by a pair of resistance heaters 17, 18 and the bimetallic spring 14 is heated by a pair of resistance heaters 19, 20. The pairs of heaters are connected in parallel in the main circuit so that each heater carries half the main current. The heaters 17, 18, 19, 20 are also supplied in series with a current proportional to the supply voltage from a secondary winding 21 wound over the voltage winding 10 of the meter 1. A centre tapping on the winding 21 is connected to the series winding 11, 12. The bimetallic spring 13 is heated in accordance with the vector difference of the current and voltage components, whereas the bimetallic spring 14 is heated in accordance with their vector sum, so that the pointer 16 indicates power. The secondary winding 21 is formed from a copper tape the width of which is a substantial part of the length of the voltage winding 10. As shown in Fig. 2 the width is equal to the length of the winding 10, over which it is wound to form two turns which may be insulated from one another by insulating varnish or by a ribbon 26, Fig. 3, of fibre or cellulose acetate. The terminals 22, 23, 24 comprise insulated wire stripped at the ends and soldered, welded, or brazed to the ribbon. Grooves 22a, 23a, 24a may be provided in the ribbon, for 'receiving the terminals. In a modification for a three-phase meter a second similar secondary winding is wound over the winding 21.

Filed: 1942-03-14
Abstract: 556,175. Automatic control systems for moving bodies ; magnetic tests. GALL, D. C. March 14, 1942, Nos. 3402 and 3892. [Class 38 (iv)] [Also in Groups XXXVI and XL] Steering.-A balanced magnet 1, which is polished or carries a mirror, is associated with a magnetic inducing element constituted for example by bars c, c<SP>1</SP> of high permeability. When a magnetic field in which the magnet lies is not normal to the axis of the inducing element a deflection of the magnet occurs which varies the light which it reflects on a photo-electric cell 6. The cell is adapted to control an electric relay R or an indicating, measuring or recording instrument whereby changes in the relative direction of the magnetic field may be utilized, measured or recorded. The cell 6 may be connected in series with a condenser 7 in an A.C. circuit connected to the grid of a gas filled triode 8, energized from the same source, whereby phase displacements of grid voltage cause variations in the output of the valve which actuate the relay R to initiate' corrective steering of a moving body on which the apparatus is installed. Devices arranged respectively normal to the horizontal component and to the angle of dip of the earth's magnetic field may control or give indications of changes in course and height of the moving body. The output current of the valve may energize a coil or coils arranged (for example, as shown), to increase or decrease the field deflecting the magnet according as increased sensitivity or stability is desired. The magnet may be suspended on a taut fibre in a transparent case filled with a transparent damping liquid. According to the first Provisional Specification the case may, alternatively, be evacuated.

Filed: 1929-02-01
Abstract: 305,179. Kn³ttel, E. Feb. 1, 1928, [Convention date]. Density separators; discharging.-The closing members of a continuously operating centrifugal machine are operated by means of an electric motor surrounding the main shaft of the machine. The stator b and its casing d are rigidly fixed to the main shaft e, and slip rings c are used for the supply of current. The rotor a is mounted on a threaded sleeve f which rotates on the main shaft but cannot move axially. The sleeve f engages a threaded sleeve h which can move axially on the shaft but cannot rotate on it. The sleeve h is attached to the opening and closing member i. All the parts normally rotate with the shaft without any relative movement. When it is desired to open the machine, current is supplied to the motor through the slip rings. The rotation of the rotor relative to the main shaft causes the sleeve h to move axially to operate the member i. The member i may be operated by a rotary motor or by combined rotary axial motions.
